SQL中自定义拆分为新表的函数

 /*按照符号分割字符串*/
create function [dbo].[m_split](@c varchar(2000),@split varchar(2))   
  returns @t table(col varchar(200))   
  as   
    begin   
      while(charindex(@split,@c)<>0)   
        begin   
          insert @t(col) values (substring(@c,1,charindex(@split,@c)-1))   
            set @c = stuff(@c,1,charindex(@split,@c),'') 
           -- SET @c = substring(@c,charindex(' ',@c)+1,len(@c))     
        end   
      insert @t(col) values (@c)   
      return   
end
 
select * from dbo.m_split('1,2,3,4,5',',')
